Many areas of Zephyr divide and round up without using the DIV_ROUND_UP
macro. Make use of it, so that we make use of a tested system macro and
at the same time we make code more readable.

Unify the drivers/*/Kconfig menuconfig title strings to the format
"<class> [(acronym)] [bus] drivers".
Including both the full name of the driver class and an acronym makes
menuconfig more user friendly as some of the acronyms are less well-known
than others. It also improves Kconfig search, both via menuconfig and via
the generated Kconfig documentation.

Since PINCTRL and pinctrl-0 is now required, there's no point in doing
extra validation at driver level. Modify the macro to just check that
sleep state is present when needed, since it was the only remaining
assertion that was not covered. Renamed the macro to make it more clear
what it does: NRF_DT_CHECK_NODE_HAS_PINCTRL_SLEEP

When the PAUSE or STOP command was triggered, the driver was first
requesting the PDM peripheral to stop by calling nrfx_pdm_stop() and
then it was setting a flag that was in turn checked in an interrupt
that was generated when the PDM actually stopped (what happens a moment
after the stop request is made). But that setting of the flag could get
preempted and the interrupt handler could get executed first causing
the stopping to be not handled properly and leaving the driver falsely
considering the peripheral as still active.
This commit reverses the order of these two operations to avoid
the described race condition.
Same sequence is corrected also in event_handler(), but this is
done only for consistency (it is in the interrupt handler itself
so there is no race possible in this case).

Change automated searching for files using "IRQ_CONNECT()" API not
including <zephyr/irq.h>.
Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

Instead of selecting appropriate HAS_HW_NRF_* options for particular
nRF SoCs (and simulated nRF52 target), set their values basing on
information from devicetree.
Correct also semantics of those options so that they are set only when
a corresponding DT node is enabled. This allows using them directly in
Kconfig dependencies of Zephyr drivers for nRF peripherals. Update
appropriately these dependencies.

Extend the macro with checks for DT properties related to pin
assignments that are defined but would be ignored, depending on
whether PINCTRL is enabled or not, what presumably indicates
a resulting configuration different from what the user expects.
Add also a possibility to indicate that the pinctrl-1 property
should not be checked because the caller does not support the
sleep state.
Rename the macro so that its name better reflects its function.
Update accordingly all drivers that use it.

Shims for nrfx drivers should only connect the related IRQ handlers,
they should not enable the IRQs, as this could lead to a situation
where the interrupt handler is called before the driver had a chance
to properly initialize the peripheral and install the provided event
handler. nrfx drivers will enable the interrupts appropriately on
their own by calling the NRFX_IRQ_ENABLE macro which is implemented
in nrfx_glue.h as a call to irq_enable().
This commit fixes the above issue spotted in the following shims:
- dmic_nrfx_pdm
- clock_control_nrf
- i2s_nrfx

Add a shim that allows using the nrfx PDM driver via the Zephyr API.
Add also missing devicetree nodes representing the PDM peripherals
in the nRF52 Series SoCs.
Extend the "nordic,nrf-pdm" binding with a new property that allows
specifying the clock source to be used by the PDM peripheral (so that
it is possible to use HFXO for better accuracy of the peripheral clock
or, in the nRF53 Series SoCs, to use the dedicated audio oscillator).
